One of the common questions asked by people hoping to have a loft conversion, is whether or not planning permission is required.The answer is, no not really, but it depends. If you're not ready to hire a builder or an architect yet, there are ways to answer this question a little better.

The total conversion space isn't greater than 40 cubic metres for terraced houses or 50 cubic metres for semi-detached and detached houses

The materials used look similar to your house

Your house isn't on conservation site, national park etc

Any side windows are 1.7metres or more above the floor

If you are unsure then just contact a builder or architect and they can help you

Building RegulationsWhilst you might not need to get planning permission, you will need to ensure that your loft extension meets specific building regulations.The type of conversion that you go for will have set regulations that need to be met, but on a more general basis, these include;

Access – predominately this means fitting stairs.New stairs will need to be fitted to ensure that there is an adequate escape route in the event of a fire

Flooring – you will need to invest in new flooring for your conversion and this will also mean fitting new floor joists that can support the overall weight of your new room

Fire safety – as well as an escape route, you'll need to have fire resistant doors fitted and smoke alarms are always a good idea

Walls – if you are having new walls fitted as part of your loft conversion, then you will need to ensure that these are strong enough to support your roof if any previous supports have been removed

Sound insulation – one of the many things that missed is sound insulation.It's always a good idea to make sure that there is sufficient insulation between rooms and this includes any sound travelling down from your conversion

The above lists aren't extensive and you'll find that there are many other things that need to be considered before having a loft conversion constructed.Whilst planning permission isn't always needed, there are circumstances when it will be required.Regardless of whether or not planning permission is required, there are building regulations that must be met.
